• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ((tai hoc) OR (dai hoc)) sach nha thu thang ) OR ( tu sach dao duc anh ho thu thong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ((tai hoc) OR (dai hoc)) sach nha thu thang ) or ( tu sach dao duc anh ho thu thong ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach ((tai hoc) OR (dai hoc)) sach nha thu thang ) or ( tu sach dao duc anh ho thu thong ))*.
